The EtherCATEtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs unique ID option will write a unique identifier into each EtherCAT device. It can be enabled or disabled in the IDE"Integrated development environment"
An integrated development environment is a type of computer software that assists computer programmers in developing software.
IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and a debugger, from the Project View -> EtherCAT -> XML"Extensible Markup Language "
XML is a general-purpose markup language. It is classified as an extensible language because it allows its users to define their own tags Configuration File tab. If the unique ID option is enabled, the unique ID will be stored in the AKD backup. Later, when the drive is replaced and restored, the same unique ID will be restored to the replacement drive.
When the unique ID option is enabled, a replacement drive must be restored before the PLC"Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events program can be started. If the option is disabled, then the PLC program can be started without checking that the replaced drive has been restored.
If you enable the Autostart option in the controller and you plan to use the AKD Backup and Restore functions, it is strongly recommended that you enable the unique ID option. This will prevent the controller from automatically starting a PLC application with a replacement AKD, that has not been restored.
